Inside tube is made from Ceramic material to provide excellent thermal isolation between heater and cooling block. And copper for heat dissipation to accelerate heat conduction. And Can reach up to 550C degree. Very low thermal conductivity and Low surface friction coefficientThe hardness of ceramic is second only to diamond and it is extremely wear-resistant. Long-term use of carbon fiber or glass fiber reinforced filament. And Very hard-wearing treatmentCompatible with Creality Ender 3 Neo Ender 3 V2 Neo Ender 3 Max Neo CR-6 SE CR-6 Max CR-5 PRO CR10 Smart 3D Printer.
